Method for manufacturing tertiary amine

Abstract

The invention provides a method for manufacturing a tertiary amine, including reacting a tertiary amine with an alcohol and a primary or secondary amine in a reactor loaded with a film type catalyst, controlling the superficial velocity of liquid in the reactor at 0.1 cm/s or more.

1. A method for manufacturing a tertiary amine, comprising the step of reacting a tertiary amine with an alcohol and a primary or secondary amine in a reactor loaded with a film type catalyst, controlling the superficial velocity of the reactor at 0.1 cm/s or more. 
     
     
       2. The method for manufacturing a tertiary amine according to  claim 1 , wherein the reaction is carried out by disposing the reactor in an outside circular line ancillary to a buffering tank loaded with no catalyst and circulating the reacting liquid to the reactor. 
     
     
       3. The method for manufacturing a tertiary amine according to  claim 1  or  2 , wherein the film type catalyst is fixed on the surface of a support and the thickness of the catalyst is 0.01-500 μm. 
     
     
       4. The method for manufacturing a tertiary amine according to  claim 1  or  2 , wherein the alcohol is a linear or branched, saturated or unsaturated aliphatic alcohol having 8-36 carbon atoms. 
     
     
       5. The method for manufacturing a tertiary amine according to  claim 1  or  2 , wherein the primary or secondary amine is an aliphatic primary or secondary amine.
